High-Voltage Gas Arresters

High-voltage gas arresters (also known as HGA) are an important component within electrical systems. They are used to protect electrical systems from electrical surges due to lightning strikes or other unexpected power occurrences. This article discusses the application field and the working principle of HGA and how they are used.

What are High-voltage Gas Arresters?

An HGA is a device which typically consists of two or more non-conductive components—an insulator, a conductor, and a gas. It is designed to suppress the high-voltage currents that can be caused by a lightning strike or other electrical surge in order to protect equipment from any electrical damage. These devices are commonly used in power distribution systems, power plants, and telecommunications systems.

Application Field of High-voltage Gas Arresters

High-voltage gas arresters have a variety of applications in electrical systems. In power distribution systems, these arresters are used to protect the equipment from strong currents that could damage it, such as those caused by lightning strikes. This type of arrester is also used in power plants and telecommunications systems to protect against power outages and surges. In addition, they can be used to protect against the risk of fire in hazardous locations.

Working Principle of High-Voltage Gas Arresters

High-voltage gas arresters work by letting only a limited amount of current pass through them. The device is composed of a series of sealed cells, each equipped with an insulator and a conductor. When a high-voltage surge enters the arrester, the insulator traps the energy. The conductor helps redirect the energy to the ground. The gas is there to provide a safe passage for the energy to be dispersed without causing any damage.

Conclusion

High-voltage gas arresters are an important component in electrical systems, as they provide protection against electrical surges and outages. HGAs can be used in power distribution systems, power plants, and telecommunication systems. They work by trapping the energy and then redirecting it to the ground, providing a safe passage for it. This helps to protect equipment and mitigate the risk of fire in hazardous locations.
